Autogenous venous grafts ten years later

Area of Science:

• Vascular Surgery
• Cardiovascular Research
• Medical Statistics

Background:

• Autogenous venous femoropopliteal bypass grafts are crucial for limb salvage.
• Long-term outcomes and graft patency rates are essential for patient counseling.

Purpose of the Study:

• To report the 10-year outcomes of femoropopliteal bypass grafts.
• To analyze factors influencing graft patency and patient survival.

Main Methods:

• Prospective follow-up of 103 patients with 113 bypass grafts over 10 years.
• Data collection included patient survival, graft patency, cause of death, and clinical indication.
• Graft patency was assessed by arteriography and clinical status.

Main Results:

• 10-year mortality rate was 73% (75/103), with myocardial infarction as a leading cause.
• Overall graft patency at 10 years was 38% (11/29) for survivors.
• Graft patency was significantly lower for rest pain/gangrene indications (14%) compared to claudication (45%).
• Short grafts (43%) showed better patency than long grafts (25%).
• Good limb runoff correlated with better graft patency (41%) than poor runoff (29%).

Conclusions:

• Long-term survival after femoropopliteal bypass is limited, with high mortality and declining graft patency.
• Graft patency is influenced by surgical indication, graft length, and limb runoff.
• Accurate reporting and patient expectation management are critical for long-term prognosis discussions.
